【正文】 nanoparticles insulate infrared and electromagic wave has two main aspects: ? The size of nano particle is much smaller than the infrared‘s and radar wavelength’s, so the wave transmissivity（透射率） of nanoparticles materials is much stronger than conventional materials‘. This greatly reduced wave reflectivity（反射率） and weakened the received reflection signals of infrared and radar, achieving the effect of stealth. ? The surface area of nanometer particle material is much larger than conventional coarse powder39。s, in a result, the waveabsorbing rate of infrared light and electromagic is higher than conventional materials39。. This reduced the intensity of the reflected signal of the infrared sensor and radar. Therefore, it is difficult to find the object being detected and so the insulation effect works. B2 通體烏黑，無(wú)機(jī)身、無(wú)前翼、無(wú)尾翼，又喜歡在若暗不明的夜空出沒，象“黑色幽靈”。 是目前世界上最居代表性的隱身兵器。 ? Application: If strategic bombers （戰(zhàn)略轟炸機(jī)） , missiles（導(dǎo)彈） and the surface of aggressive aircrafts （攻擊性飛行器） are smeared with nano waveabsorbing materials, the enemy air defense radar（敵方防空雷達(dá)） electromagic wave is absorbed effectively(B2 stealth bomber surface coating contains nano material). ? It is good to insulation effect if the nanoparticles are added into the fuming agent（發(fā)煙劑） and it also insulate underground headquarters and other important military facilities if it is mixed with the soil. F22已經(jīng)成為美國(guó)空軍在 21世紀(jì)的主力制空戰(zhàn)斗機(jī)，能攜載 8枚空 對(duì)空導(dǎo)彈，并具先進(jìn)航空電子傳感系統(tǒng)， 大大提高了飛行員對(duì)周 邊環(huán)境的認(rèn)知能力以及在被敵方發(fā)現(xiàn)之前跟蹤、攻擊敵機(jī)的能力。 這種戰(zhàn)機(jī)還具有較強(qiáng)的地面攻擊能力，可在超音速飛行的情況下 精確投擲衛(wèi)星制導(dǎo)炸彈，其速度更勝其他戰(zhàn)斗機(jī)。 Thank u for listening！?。?
